To move the conversation away from the particular, think about programming languages as just that, languages. The universal language is, of course, mathematics. Each programming language is another way to express those relationships. Granted they are different, but I disagree that learning another language requires 'unlearning'. I think the power of learning additional languages is the capacity to get your mind around problems in different ways. Different problems require different tools. I would think a company would rather hire a multi-lingual programmer who can find the best solution for a given problem.

My son, a FIRSTer who is now an ME at Electric Boat, learned C for FIRST, Labview at WPI, then used an Arduino for his capstone project. When a certain problem required a unique approach, he was the only ME in his group with the requisite programming skills to handle the problem.

So look at learning a number of programming languages as building a toolkit for your future!
